IMPROVEMENT IN VENTILATORS FOFA SHOP-WINDOWS.

Spccitcaton forming part of Letters Patent No. 38,675, dated May 26, 1863.

To @ZZ whom it may concern.:

Be it known that I, HENRY A. GoUGE, of Brooklyn, Kings county, and State of New York, have invented a new and Improved Ventilator for Store-Windows and Stores; and .Ihereby declare thatgthe followin gis a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part ot' this speciication, and the letters of reference marked thereon, in which the same letter represents the same thing in each figure.

Figure 1 is an exterior front eleva-tion showing the interior arrangement; Fig. 2, a crosssection of the retlector and gas-burner; Fig. 3, a vertical cut section 5 Fig. 4, a plan view of the base of the ventilator; Fig. 5, a cut section of the same, and Fig. 6 a bottom view thereof.

Letter A represents the bottom and sides of the ventilated apartment; B, the reflector 5 C, the Ventilating-pipe D, the illuminating-gas pipe; E, the Ventilating gas-pipe, F, the feedpipe to the illuminating-gas burner; J, the cold-air register; K, the perforated back plate thereof 5 L, the slide-door beneath register J 5 N, the slide-door to close holes m m m2 beneath the bottom of the window-sill, P, the narrow open space between the inclined plate V and the front glass ofthe window', R, the Ventilating-door at the top of the window; T, the inside window-door 5 V, an inclined plate, extending t'x om the bottom of the window-sill toward and close to the front window glass; V, the ventilating gas-burner; it. i2, valves to holes 7L h h2 at the top of the reector, m m m2, holes beneath the inclined plate V.

The object of my improvement is the ventilation of store-windows, at the same time securing facilities for the ventilation of the store itself; but a more import-ant object secured by my invention is the prevention of the conv densation of moisture on the inside of storewindows in cold weather by equalizing the temperature on the inside with the outside ot' the glass as nearly as possible. This is effected by creating heat near the top of the window, which, rarefying the air, promotes its escape through ventilating-pipe C, While it causes a current to be supplied with cold air from the bottom of the window-sill.l In the evening this heat is obtained from the illuminating-gas burner D in the day, by the Ventilating gasburner W. Sliding door AL over opening J in the bottom of the window-sill regulates the amount of air admitted, and similar door N controls the admission of air through holes m m m2, directed by inclined plate V against theinside of the window-plate, which it reaches through passage P, thereby securing cool air to that surface of the window-plate and pre ven ting condensation of the moisture thereon. Opening door R and valves it" Ai2 will assist in the ventilation ot' the store.

What I claim, and desire to secure by Letters Patent, is-

1. The inclined plate V,in combination with holes m m m2 and passage P, to divert the current of incoming air directly upon the inside ofthe window, substantially in the manner described.

2. The combination of Ventilating-tube C,

with passage P and holes m m m2, or their equivalents, constructed and operating together substantially as and for the uses set forth.
